 # @push.rocks/smartssh
-setups SSH quickly and in a painless manner
 
-## Availabililty and Links
+Secure SSH configuration, key management, and remote machine control for modern TypeScript projects. `@push.rocks/smartssh` gives you two things in one focused package: safe local OpenSSH config/key orchestration and a promise-first SSH client for executing commands, opening shells, transferring files, and forwarding ports.

-* [docs (typedoc)](https://push.rocks.gitlab.io/smartssh/)
 
-## Status for master
+Built on top of the pure JavaScript `ssh2` engine, it keeps the low-level protocol details out of your application while still exposing the control you need for serious automation.

-```javascript
+## Install
-var smartssh = require('smartssh');
+
-var sshInstance = new smartssh.sshInstance({
+```bash
-  sshDir: '/some/path/.ssh', // the standard ssh directory, optional, defaults to "~./.ssh"
+pnpm add @push.rocks/smartssh
-  sshSync: true, // sync ssh this instance will represent the status of an ssh dir if set to true;
+```
+
+## What It Does
+
+- Manage SSH keys as typed `SshKey` objects.
+- Generate OpenSSH-compatible config files with secure defaults.
+- Read managed key material back from disk.
+- Connect to remote machines with `SshClient`.
+- Execute commands and collect stdout, stderr, exit code, and signal.
+- Stream long-running commands or start interactive shells.
+- Use SFTP for uploads, downloads, file reads, writes, stats, permissions, and directory operations.
+- Forward TCP connections through SSH.
+- Verify host keys by SHA256 or MD5 fingerprints, with explicit opt-out for disposable test systems.
+
+## Quick Start
+
+```typescript
+import { SshClient, SshKey } from '@push.rocks/smartssh';
+
+const privateKey = SshKey.fromFile('/home/deploy/.ssh/id_ed25519');
+
+const sshClient = await SshClient.connect({
+  host: 'server.example.com',
+  username: 'deploy',
+  privateKey,
+  trustedHostFingerprints: ['SHA256:replaceWithYourKnownHostFingerprint'],
+});
+
+const result = await sshClient.exec('uname -a');
+
+console.log(result.code);
+console.log(result.stdout);
+console.error(result.stderr);
+
+await sshClient.close();
+```
+
+## Secure Defaults
+
+`smartssh` is intentionally conservative:
+
+- SSH config generation writes `StrictHostKeyChecking yes` by default.
+- `SshClient.connect()` requires host validation by default.
+- Private key files are written with `0600` permissions.
+- Public key files are written with `0644` permissions.
+- SSH directories are created with `0700` permissions.
+- Host aliases are validated before they are used as filenames or config entries.
+
+For local throwaway test servers you can explicitly opt out of host checking:
+
+```typescript
+const sshClient = await SshClient.connect({
+  host: '127.0.0.1',
+  username: 'tester',
+  password: 'secret',
+  strictHostKeyChecking: false,
+});
+```
+
+Do not disable host checking for production infrastructure unless another trust layer is already enforcing host identity.
+
+## Key Management
+
+Create keys in memory:
+
+```typescript
+import { SshKey } from '@push.rocks/smartssh';
+
+const githubKey = new SshKey({
+  host: 'github.com',
+  private: process.env.GITHUB_PRIVATE_KEY,
+  public: process.env.GITHUB_PUBLIC_KEY,
+});
+
+console.log(githubKey.type); // 'duplex', 'private', 'public', or undefined
+console.log(githubKey.privKeyBase64);
+```
+
+Load keys from files:
+
+```typescript
+const deployKey = SshKey.fromFile('/home/deploy/.ssh/id_ed25519');
+
+const combinedKey = SshKey.fromFiles({
+  host: 'production-app',
+  privateKeyPath: '/home/deploy/.ssh/production-app',
+  publicKeyPath: '/home/deploy/.ssh/production-app.pub',
+});
+```
+
+Store keys safely:
+
+```typescript
+await combinedKey.store('/home/deploy/.ssh');
+```
+
+## OpenSSH Config Management
+
+Use `SshInstance` when you want to manage a whole SSH directory and config file.
+
+```typescript
+import { SshInstance, SshKey } from '@push.rocks/smartssh';
+
+const sshInstance = new SshInstance({
+  sshDirPath: '/home/deploy/.ssh',
+  strictHostKeyChecking: true,
 });
 
 sshInstance.addKey(
-  new smartssh.sshKey({
+  new SshKey({
-    private: 'somestring',
+    host: 'git.example.com',
-    public: 'somestring', // optional
+    private: process.env.GIT_PRIVATE_KEY,
-    host: 'github.com',
+    public: process.env.GIT_PUBLIC_KEY,
-    encoding: 'base64', // optional, defaults to "utf8", can be "utf8" or "base64", useful for reading ssh keys from environment variables
   })
 );
 
-sshInstance.removeKey(sshInstance.getKey('github.com')); // removes key for host "github.com" is present
+sshInstance.writeToDisk();
-
-sshInstance.createKey({
-  host: 'gitlab.com', // returns new key in the form sshKey, read more about the sshKey class below
-});
-
-sshInstance.getKey({
-  // returns ssh key in the form sshKey, read more about the sshKey class below
-  host: 'github.com',
-});
-
-sshInstance.getKeys(); // returns array of all available getKeys. Each key is in form of class sshKey
 ```
 
-## Contribution
+Generated config example:
 
-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+```sshconfig
+Host git.example.com
+  HostName git.example.com
+  IdentityFile /home/deploy/.ssh/git.example.com
+  StrictHostKeyChecking yes
+```
 
-For further information read the linked docs at the top of this readme.
+Read keys back from disk:
 
-## Legal
+```typescript
-> MIT licensed | **©** [Task Venture Capital GmbH](https://task.vc)
+const existingSsh = new SshInstance({
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+  sshDirPath: '/home/deploy/.ssh',
+});
+
+existingSsh.readFromDisk();
+
+const key = existingSsh.getKey('git.example.com');
+console.log(key?.pubKey);
+```
+
+## Remote Command Execution
+
+`exec()` waits for the remote command to finish and returns a structured result.
+
+```typescript
+const result = await sshClient.exec('systemctl is-active nginx', {
+  timeout: 10_000,
+});
+
+if (result.code !== 0) {
+  throw new Error(result.stderr);
+}
+
+console.log(result.stdout.trim());
+```
+
+Send input to a command:
+
+```typescript
+const result = await sshClient.exec('cat > /tmp/message.txt', {
+  input: 'hello from smartssh\n',
+});
+```
+
+Abort or time-limit a command:
+
+```typescript
+const abortController = new AbortController();
+
+setTimeout(() => abortController.abort(), 5_000);
+
+await sshClient.exec('sleep 60', {
+  signal: abortController.signal,
+});
+```
+
+## Streaming Commands and Shells
+
+Use `stream()` for long-running commands where you want to handle output as it arrives.
+
+```typescript
+const stream = await sshClient.stream('tail -f /var/log/syslog');
+
+stream.on('data', (chunk) => {
+  process.stdout.write(chunk);
+});
+
+stream.stderr.on('data', (chunk) => {
+  process.stderr.write(chunk);
+});
+```
+
+Start an interactive shell:
+
+```typescript
+const shell = await sshClient.shell({
+  window: {
+    rows: 40,
+    cols: 120,
+    term: 'xterm-256color',
+  },
+});
+
+shell.write('whoami\n');
+shell.write('exit\n');
+```
+
+## SFTP
+
+Create an SFTP client from an active SSH connection:
+
+```typescript
+const sftp = await sshClient.sftp();
+```
+
+Upload and download files:
+
+```typescript
+await sftp.upload({
+  localPath: './dist/app.tar.gz',
+  remotePath: '/tmp/app.tar.gz',
+});
+
+await sftp.download({
+  remotePath: '/var/log/app.log',
+  localPath: './app.log',
+});
+```
+
+Read and write remote files:
+
+```typescript
+const osRelease = await sftp.readFile('/etc/os-release', 'utf8');
+
+await sftp.writeFile('/tmp/deploy.json', JSON.stringify({
+  version: '1.2.3',
+}));
+```
+
+Inspect and manage remote paths:
+
+```typescript
+const files = await sftp.readdir('/var/www');
+const stats = await sftp.stat('/var/www/app');
+
+await sftp.mkdir('/tmp/smartssh');
+await sftp.chmod('/tmp/smartssh', 0o755);
+await sftp.rename('/tmp/old-name', '/tmp/new-name');
+await sftp.remove('/tmp/new-name');
+```
+
+## Port Forwarding
+
+Open a direct TCP channel through the SSH server:
+
+```typescript
+const channel = await sshClient.forwardOut({
+  destinationHost: '127.0.0.1',
+  destinationPort: 5432,
+});
+
+channel.write('raw tcp payload');
+```
+
+Ask the remote SSH server to listen and forward incoming TCP connections:
+
+```typescript
+const forward = await sshClient.forwardIn({
+  remoteHost: '127.0.0.1',
+  remotePort: 0,
+});
+
+console.log(`Remote port: ${forward.remotePort}`);
+
+await forward.close();
+```
+
+## API Overview
+
+### `SshClient`
+
+- `SshClient.connect(profile)` creates and connects a client in one step.
+- `connect()` opens the SSH connection for an existing instance.
+- `exec(command, options)` runs a command and returns `ISshExecResult`.
+- `stream(command, options)` opens a command channel for streaming output.
+- `shell(options)` starts an interactive shell channel.
+- `sftp()` returns a typed `SshSftpClient`.
+- `forwardOut(options)` opens a direct TCP channel through SSH.
+- `forwardIn(options)` creates a remote listener and returns a closeable handle.
+- `close()` ends the connection.
+- `fingerprintSha256(key)` and `fingerprintMd5(key)` generate comparable host key fingerprints.
+
+### `SshSftpClient`
+
+- `upload({ localPath, remotePath })`
+- `download({ remotePath, localPath })`
+- `readFile(remotePath, encoding?)`
+- `writeFile(remotePath, data)`
+- `readdir(remotePath)`
+- `stat(remotePath)` and `lstat(remotePath)`
+- `mkdir(remotePath, attributes?)`
+- `chmod(remotePath, mode)`
+- `rename(sourcePath, destinationPath)`
+- `remove(remotePath)` and `rmdir(remotePath)`
+
+### `SshKey`
+
+- Construct with `{ host, private, public, authorized }`.
+- Read and write private/public key strings.
+- Encode and decode key material with `privKeyBase64` and `pubKeyBase64`.
+- Load keys from disk with `fromFile()` or `fromFiles()`.
+- Store keys to disk with safe permissions via `store()`.
+- Inspect `type` as `duplex`, `private`, `public`, or `undefined`.
+
+### `SshInstance`
+
+- `addKey(key)`, `removeKey(key)`, and `replaceKey(oldKey, newKey)` manage key collections.
+- `getKey(host)` retrieves a managed key by host alias.
+- `sshKeys` exposes the current key array.
+- `writeToDisk(dirPath?)` writes keys and config.
+- `readFromDisk(dirPath?)` reads key files from an SSH directory.
+- `sshSync: true` keeps disk state in sync on key changes.
+
+### `SshConfig`
+
+- `store(dirPath)` writes an OpenSSH config file.
+- `read(dirPath)` reads the config file.
+- `parse(dirPath)` parses host blocks from a config file.
+- `SshConfig.parse(configString)` parses host blocks from a string.
+
+## Types You Will Usually Import
+
+```typescript
+import type {
+  ISshProfile,
+  ISshExecOptions,
+  ISshExecResult,
+  ISshUploadOptions,
+  ISshDownloadOptions,
+  ISshForwardInHandle,
+  ISshForwardInOptions,
+  ISshForwardOutOptions,
+  ISshShellOptions,
+  TSshHostVerifier,
+} from '@push.rocks/smartssh';
+```
+
+## Real-World Flow
+
+```typescript
+import { SshClient, SshKey } from '@push.rocks/smartssh';
+
+const key = SshKey.fromFile('/home/deploy/.ssh/production');
+
+const server = await SshClient.connect({
+  host: 'app-01.example.com',
+  username: 'deploy',
+  privateKey: key,
+  trustedHostFingerprints: ['SHA256:replaceWithTheRealFingerprint'],
+  keepaliveInterval: 30_000,
+});
+
+try {
+  const sftp = await server.sftp();
+
+  await sftp.upload({
+    localPath: './release.tar.gz',
+    remotePath: '/tmp/release.tar.gz',
+  });
+
+  const deploy = await server.exec([
+    'set -e',
+    'mkdir -p /srv/app',
+    'tar -xzf /tmp/release.tar.gz -C /srv/app',
+    'systemctl restart app',
+  ].join(' && '), {
+    timeout: 120_000,
+  });
+
+  if (deploy.code !== 0) {
+    throw new Error(deploy.stderr);
+  }
+} finally {
+  await server.close();
+}
+```
+
+## Notes
+
+- The package is ESM-first and intended for TypeScript projects.
+- `ssh2` is used directly as the SSH protocol engine.
+- Config generation is intentionally simple and focused on managed host/key entries.
+- `readFromDisk()` reads key files from the SSH directory; it does not attempt to preserve or rewrite arbitrary user-managed config comments.
+- Host aliases are intentionally restricted to filename-safe values to avoid path traversal and config injection.
